DOZENS of “unstoppable” hypersonic missiles fired from destroyers will be ready to strike anywhere in the world at up to 13,000mph under plans drawn up the the US Navy.
Its most advanced warships are due to be upgraded to carry new “boost-glide” weapons so fast they cannot be shot down.
Details of the plans emerged as the Pentagon races to catch up with advances in hypersonic missile technology in Russia and China.
Vladimir Putin is said to be planning a new test of his world-ending Satan-2 ICBM nuke, and claims a range of smaller hypersonic weapons are already deployed.
In response the US Army and US Navy have been jointly developing a futuristic craft designed to skim the atmosphere at incredible speed.
